The problem began early today. “We're investigating reports of an issue with Google Calendar,” the company wrote on a status update page at 9:47 a.m E.D.T. Less than an hour later, the company said they were still investigating the issue, and by 11:33 a.m., they said that “Google Calendar service has already been restored for some users, and we expect a resolution for all users in the near future.”

The term “Google Calendar” became a trending topic on Twitter on Thursday, with one much-retweeted tweet time-stamped at 9:40 a.m. proclaiming, “Google Calendar is down. All meetings are canceled. Everyone go home.”
